Script to change the BIOS VMX. UUID value?

Due to how transfer us models of VM to stand-alone ESXi 4.1 guests before their junction to vCenter, the UUID for the models come out the same. We use Veeam Backup to restore the templates, so they can be compressed enough to fit on a DVD.

I'm looking for a little PowerShell script that can define a custom BIOS. Value of UUID for a VM named on ESXi 4.1. 1002403 KB VMware has a Pearl script that allows you to do this, but we are a store of PowerShell and would make it easier for us to customize in the future. Ideally, the script would generate a UUID Pseudo-aleatoires without user intervention. For example, to set the last six digits to use the current month, day, and minute (MMDDMM, for example 100111).

vCenter will create of course unique UUID for our production of VMs, so it's only to manage the initial models, that we download to standalone servers in "factory".

Ideas?

Try something like this

$vmName = 
$newUuid = 

$spec = New-Object VMware.Vim.VirtualMachineConfigSpec
$spec.uuid = $newUuid
$vm = Get-VM -Name $vmName
$vm.Extensiondata.ReconfigVM_Task($spec)

Note that the call to the method it is more simple forms, not waiting for the completion of the task, no error checking.

  • Script to change the name of the file to the virtual machine and its associated files

    Hello

    I'm looking for a script to change the name of the virtual machine in virtual center and also change it has associated file names in the data store to match file name of virtual machine. But the vmdk file will contain a descriptor which maps the - flat.vmdk file. So not sure that we can achieve this through a script.

    Thanks in advance!

    Not really as much as I know.

    The advantage of the svMotion is renamed it the files (.) VMX, VMDK,...) For you.

    The only alternative would be the command line. See Duncan Howto: renaming a virtual computer.

    With the help of the plink.exe tool which could possibly be scripted.

  • Satellite 1000-S158 changed the BIOS password on an empty

    I changed the BIOS password on an empty (blank). I can't access the BIOS. Pressing on enter: it shows the error isn't the right password.
    How can I fix?

    Hmm. sounds you did something wrong maybe you misspelled or set a different password?

    Anyway, the point is that you are not able to bypass the BIOS password screen and in this case you will be unable to start Notepad.

    The problem is that you cannot remove the BIOS password, this can be done by a technician of ASP.

    In my opinion only technician in ASP can help you.

    If someone has the original settings, I would be grateful for any help.

    Hello Derek

    Use the F2 key to enter the BIOS settings and change the order of boot devices. This option is under the STARTUP tab. Otherwise, you can insert the recovery CD when the unit is turned OFF. Turn it on and immediately press the C button. keep it down for a few seconds and unit is forced from the CD/DVD drive.

    You may or may not need to change the BIOS settings.  Assuming that you have a bootable CD with this tool, put it in your CD drive and restart the computer.  One of the 3 things will happen:

    1. the computer starts from the CD and you can follow all instructions you have Symantec.

    2 watching very carefully that the computer starts.  You may see a message that says something like "press any key to boot from the CD-ROM.  If you see this message, press a key (for example, the space bar) and the computer boots from the CD.

    3. watch very carefully that the computer starts.  You will see a message that says something like, "to change settings, press F1."  The key that you press on will be different depending on your particular computer.  It might be F1 or F10 or del key.  Whatever it is, press this button and you will enter the BIOS configuration utility.  From there, you can change the boot order to CD first.  Directions to navigate the BIOS Setup will be displayed on the screen, but they will involve using the button tab, enter, and arrow keys, because your mouse does not work in this utility.

  • I restart the computer and changed the BIOs to boot from the CD. So as usual, I'm prompted to press any key to start from the CD or DVD.

    Hello Comunity Microsoft :D My name is Mike and I built a gaming pc. Everything was going well for the first 3 days, but now I have a few crashes very violent. Speakers in loop and buzz and screen lock. I have to completely shut down to go back to a working state. I did everything I could possibly think of to solve this problem, but I can't.

    Then. on the problem. Today, I decided that I was able to solve all the problems by reinstalling windows. I had my keys together and put the disc in. I restart the computer and changed the BIOs to boot from the CD. So as usual, I'm prompted to press any key to start from the CD or DVD. I do and I get normal loading windows files, and at the end of this road, I get the Welcome screen in windows7 with no option and a fat slider. I don't have the little box that tells me that I can fix my computer or reinstall windows, NOTHING. I tried several times and received the same result<--(Insanity: root="" meaning...="" just="" saying)="" so="" i="" called="" windows,="" or="" had="" windows="" call="" me="" rather,="" and="" the="" tech="" says="" she's="" never="" heard="" of="" such="" a="" thing="" happening,="" and="" walked="" me="" through="" all="" these="" steps="" that="" i="" have="" already="" tried....="" still="" no="" help.="" so="" i="" am="" asking="" the="" community.="" has="" this="" ever="" happened="" to="" you="" and="" how="" did="" you="" make="" it="" work.="" and="" please="" don't="" post="" a="" list="" of="" regurgitated="" back="" log="" fix="" lists.="" rest="" assured="" i="" have="" already="" done="" it="" and="" failed="" to="" receive="" a="" different="">

    Just to isolate the problem, try to download a new copy of Windows 7, and then try again:

    For 5 years, Microsoft made it fairly easy for users of the Windows 7 operating system to get reinstall media. If you have lost your support disc or installation retail collection; either it has been damaged or defective; You can download a copy of the edition that you have licensed from a membership site called Digital River. More recently, Microsoft ended the availability to reinstall media that you can download as a. File ISO in Digital River, which is a digital reproduction of an optical disc.

    It was particularly convenient for people who could not easily get the manufacturer's recovery media, did not want to pay the fees required to get or preferred a clean configuration without the software packaged manufacturers or even a recovery partition does not work. It's easy to use, all you had to do was reinstall and reactivate using the product key located on the certificate of authenticity and download all the drivers on the manufacturers website.

    Given that this option is no longer available, what are your options? See the article for more details:

    How to: What are my options for Windows 7 reinstall media?

    Make sure you scroll down and read the section:

    What to do if you cannot get your manufacturer recovery media, refuse to use or to buy it or the Microsoft Software Recovery Website does not work?

    Regarding problems with the computer itself, try to disconnect all nonessential equipment attached to it to see if the problem persists.

    I would also try switching around components such as modules of memory to see if the problem persists.

    I would also check to make sure that all components are mounted and installed correctly.

  • dcd5800 sff desktop PC: dc 5800 sff I m not able to change the bios setting

    How to get the password of the bios

    as I m having dc 5800 sff f10 bios password I forgot kindly help as I not able to change the bios setting

    Updated the BIOS will not clear the password.

    You can try pressing and the little button cmos clear yellow with the jumper removed password and see if that does anything.

    I think that the motherboard has a problem because removing the rider of P/O should have removed the password.

    Now turn you on the PC with the jumper removed, correct?

    You turn off the PC and unplug him.  You then remove the jumper P/W and then turn on the PC.

    That's when the P/W should be cleared.

    Then you shut down the computer, unplug and replace the rider of P/W.

    Concerning

    REDA

    Hello

    There is nothing built-in to Oracle SQL to do.  Maybe your front-end has certain characteristics.

    You can write dynamic SQL statements to do.  In other words, you can write a query that the output is a SQL script like this:

    ALTER TABLE TABLE_A CHANGE (A_TXT1 VARCHAR2 (5))

    A_TXT2 VARCHAR2 (10));

    ALTER TABLE TABLE_B CHANGE (B_TXT1 VARCHAR2 (5));

    with one row for each column of type CHAR.  Notice how the first line of output for each table begins with ALTER TABLE... but the later lines at the same table.  Similarly, the last line of a table (which will be the same as the first row, if the table has only one column of type CHAR) to end with a semicolon, but other lines are not.

    Here's a way to generate and execute such a dynamic script in SQL * more:

    -Disable the features that make the output easy to read, but hinder the execution
    SET FEEDBACK OFF
    SET LINESIZE 500
    SET PAGESIZE 0

    -Create fix_char.sql
    COIL c:\some_pathename\fix_char.sql

    SELECT THE CHECK BOX
    WHEN ROW_NUMBER () OVER (PARTITION BY table_name
    ORDER BY column_name
    )  = 1
    THEN 'ALTER TABLE ' | table-name
    || "CHANGE (").
    ELSE «»
    END
    ||        column_name
    ||        "VARCHAR2 (').
    ||        DATA_LENGTH
    ||        ')'
    ||        CASE
    WHEN ROW_NUMBER () OVER (PARTITION BY table_name
    ORDER BY column_name DESC
    )  = 1
    THEN '); "
    Output END AS
    Of user_tab_columns
    WHERE data_type = "CHAR".
    ORDER BY table_name
    column_name
    ;

    SPOOL OFF

    -Turn on the features that make the output easy to read, but hinder the execution
    SET FEEDBACK ON
    SET LINESIZE 80
    SET PAGESIZE 50

    -Fix_char.sql performance
    @c:\some_pathname\fix_char

    It's good to change all the CHARIOT of VARCHAR2 columns.  The CHAR data type is nothing trouble.
